Within a week of launching my Skerry one of the rubrail joint failed, fortunately not while it was in the water.
There are 2 layers and the scarf joint of the outside one failed. Nothing broke, just the epoxy joint came apart. The wood is very stiff and I had trouble getting it to bend enough in the first place.
I am considering the alternatives to repair. I epoxied the joint and clamped it closed and it is holding but I certainly consider it likely that it will fail again.
I' m thinking of either putting a brass plate 5/8 inch x 18 covering the outside of the rubrail with brass bolts to the inside. This would support the scarf joint and prevent it from opening again.
Maybe I could get away with just bolts with washers.
I thought also of actually cutting some ot the outside material including part of the offending scarf and applying a wood patch along the outside of the gunnel and putting epoxy cloth over the whole patch top and bottom plus on the outside edge.
How do you deal with gunnels when the outside layer gives way in this manner?
I have taken the Skerry out a number of times now (with clamps on the gunnels in order to eliminate the strain on the scarf joint) and I love the boat. It is everything I expected.
All the best
